Honestly, I like that advice. Crime is a symptom of societal dysfunction, something law enforcement has no real way to combat. The conventional belief that the police can enforce laws makes no sense, you would need an officer for each person who might do crime which would be totally infeasible. It’s like applying 1000 bandaids for ebola. Until our governments take responsibility for their failed citizens nothing will change and in the mean time I would rather crime done to me be as safe as possible, which might mean leaving my keys out
